As shown in FIG.
Alternatively, as shown in FIG. 5B, a fixing bar 16 can be used to connect the belts with a belt clamping width that can provide an appropriate clamping pressure. The presser roller 7 is provided at a position immediately after this width adjustment, thereby ensuring that the edges are aligned. The ears are completely brought together by the guide rollers 5, 5 as shown in FIG. 6b, but
As shown in FIG. 6a, the pulling guide roller 5a attached to the other side of the guide roller support bar 8 is still incompletely pulled, and from this state the sixth

図）位置まで移動する。(Operations of the Embodiment) First, in order to set an appropriate tightening amount depending on the retraction angle of the belt 1, the handle 12 is turned to determine the positions of the fulcrum blocks 9, 9. For example, the handle 1 is moved so that the fulcrum blocks 9, 9 move inwardly relative to each other.
2, the retraction guide roller 5a moves to 5a' (second
Figure) Move to the position.
